PREFACEThe Century City Constellation Station Air Quality Technical Memorandum (Air Quality TechnicalMemorandum) was shared with the City of Beverly Hills and the Beverly Hills Unified School District(BHUSD) in February 2017 as part of the Section 4(f) consultation process for the publicly usedrecreational facilities at Beverly Hills High School (BHHS). The memorandum was revised to addresscomments and concerns received in letters from the City of Beverly Hills on April 4, 2017 and July 24,2017, and BHSUD on April 7, 2017 and July 24, 2017. Following the public circulation of the DraftSupplemental Environmental Impact Statement (SEIS), the memorandum was then revised again toaddress comments received on the Draft SEIS requesting additional information and clarification on themethodologies used for the air quality analysis and the health risk assessment. This revisedmemorandum also reflects refined construction layout and equipment assumptions, which areidentified in Section 1.0.

Century City Constellation Station Air Quality Technical Memorandum – Revision 21.0 - Introduction

W E S T S I D E P U R P L E L I N E E X T E N S I O N P R O J E C TPage 1-1November 21, 2017

1.0 INTRODUCTIONThe Federal Transit Administration (FTA) and the Los Angeles County Metropolitan TransportationAuthority (Metro) prepared and distributed a Final Environmental Impact Statement/EnvironmentalImpact Report (Final EIS/EIR) for the Westside Subway Extension Project (now called the WestsidePurple Line Extension Project, or the Project) in March 2012. The Project was planned to be constructedin three sections (see Section 2.0. Project History and Overview,). The Final EIS/EIR identifiedenvironmental impacts and mitigations for the Project. The Metro Board of Directors approved Section 1of the Project in April 2012, followed by the approvals of Section 2 and Section 3 in May 2012. A Recordof Decision was issued by FTA in August 2012 for all three sections of the Project.

This Air Quality Technical Memorandum was prepared in support of the Supplemental EIS (SEIS), whichwas prepared in response to the Final Decision on Motions for Summary Judgment and Ruling in Regardsto Remedies (Final Decision) of the United States District Court for the Central District of California inBeverly Hills Unified School District v. Federal Transit Administration, et al ., CV 12-9861-GW(SSx) datedAugust 12, 2016. In the Final Decision, the Court remanded the matter back to the FTA to prepare aSupplemental EIS (SEIS) addressing the Court’s ruling. As it relates to air quality, the Final Decision statesthat FTA and Metro should complete:

An analysis of the of the potential public health impacts of NOx emissions duringconstruction of Constellation Station and tunneling for Subway Phase 2 and,depending on the results of that analysis, an assessment of the feasibility and efficacyof mitigation measures and alternatives to address such potential impacts.

This Air Quality Technical Memorandum addresses the Final Decision and includes the analysis of projectupdates detailed in Section 4.2.1 of this memorandum since publication of the Final EIS/EIR. In addition,this version of the memorandum incorporates the following analysis refinements and avoidancemeasures since publication of the Draft SEIS (Revision 1 of the Air Quality Technical Memorandum),including:

n Refined construction laydown, equipment and modeled sources assumptions: As the Project designcontinues to progress, refined information regarding the construction of the Project is becomingavailable. As detailed in Section 4.2.1 of this memorandum, trucking of muck moved from Area 3 toArea 2 and an extension of the tunnel ventilation exhaust ducts will be constructed to moveemissions away from the temporary classrooms for Beverly Hills High School (BHHS). The tunnelexhaust discharge was modeled as a point source rather than an area source. In addition, as detailedin Section 4.2.1.1, specific pieces of equipment are also required to be Tier 4, such as several cranes,loaders, and welding units. Other pieces of equipment are also required to be no higher than Tier 2due to safety reasons within the tunnel.

n Trucking requirements: All trucking associated with the project must be done with vehicles that aremodel year 2012 or newer and entrained road dust is also included in the revised analysis.

n Soil moisture content: The soil moisture content was increased to 16 percent from 7.9 percent toaccount for the fact that wet muck is being pulled out of the shaft rather than soil.

2.0 PROJECT HISTORY AND OVERVIEWThe Project is an approximately 9-mile heavy rail transit subway that will operate as an extension of theMetro Purple Line from its current western terminus at the Wilshire/Western Station to a new westernterminus near the West Los Angeles Veterans Affairs (VA) Hospital (Figure 2-1). The Project lies withinthe Cities of Los Angeles and Beverly Hills, and a part of unincorporated Los Angeles County in thevicinity of the Federal Building and the VA Hospital area.

The Project was planned to be constructed in three phases:

n Section 1: 3.92-mile section from the existing Wilshire/Western Station to Wilshire/La Cienega withthree new stations: Wilshire/La Brea, Wilshire/Fairfax, and Wilshire/La Cienega

n Section 2: 2.59-mile section from Wilshire/La Cienega to Century City with two new stations:Wilshire/Rodeo and Century City Constellation

n Section 3: 2.59-mile section from Century City to Westwood/VA Hospital with two new stations:Westwood/University of California, Los Angeles and Westwood/VA Hospital.

Century City Constellation Station Air Quality Technical Memorandum – Revision 23.0 - Affected Environment

W E S T S I D E P U R P L E L I N E E X T E N S I O N P R O J E C TPage 3-1November 21, 2017

3.0 AFFECTED ENVIRONMENT“Air Pollution” is a general term that refers to one or more chemical substances that degrade the qualityof the atmosphere. Individual air pollutants degrade the atmosphere by reducing visibility; they are alsoresponsible for damaging property, reducing the productivity or vigor of crops or natural vegetation,and/or reducing human or animal health. Air quality is a term used to describe the amount of airpollution the public is exposed to.

Emissions of pollutants which degrade air quality in the United States are subject to the requirements ofthe Federal Clean Air Act (CAA); the CAA is administered by the U.S. Environmental Protection Agency(USEPA). In addition to being subject to the requirements of the CAA, pollutants which degrade airquality in California are also subject to the requirements of the California Clean Air Act (CCAA). TheCCAA, as amended in 1992, requires all air quality management districts in the State to endeavor toachieve and maintain State Ambient Air Quality Standards. The California Air Resources Board (CARB)administers the CCAA statewide.

Please refer to Section 3.1 of the Westside Subway Extension Air Quality Technical Report (August 2010)for a brief description of these and other involved agencies.

3.1 National and State Ambient Air Quality StandardsAs required by the Clean Air Act, NAAQS have been established for six major air pollutants. Thesepollutants are: carbon monoxide, nitrogen dioxide, ozone, particulate matter (PM 10 and PM2.5), sulfurdioxide, and lead. The State of California has also established ambient air quality standards, known asthe California Ambient Air Quality Standards (CAAQS). These standards are generally more stringentthan the corresponding federal standards and incorporate additional standards for sulfates, hydrogensulfide, vinyl chloride, and visibility-reducing particles.

Both state and federal standards are summarized in Table 3-1. The “primary” standards have beenestablished to protect the public health. The “secondary” standards are intended to protect the nation’swelfare and account for air pollutant effects on soil, water, visibility, materials, vegetation, and otheraspects of the general welfare.

3.2 Ambient Air Quality Data3.2.1 Local MeteorologyPlease refer to Section 3.2 of the Westside Subway Extension Air Quality Technical Report (August 2010)for a description of local meteorology in the area.

3.2.2 Local Monitored Air QualityAir quality data is measured at monitoring stations throughout the state by monitors that CARB/South CoastAir Quality Management District (SCAQMD) generally maintains. The monitoring stations nearest the ProjectStudy Area are located at the VA Hospital in West Los Angeles and 1630 North Main Street in downtown LosAngeles. The West Los Angeles monitor is within the project study area and is most representative of the air

quality in the study area. This monitor, however, does not monitor PM10 or PM2.5. As such, the NorthMain Street monitor is included as an indicator of the ambient air quality in the study area. The VAhospital is located 2.5 miles from the construction area. The North Main Street monitor is located 10.5miles from the construction area. The last four years of available monitored data for these locations aresummarized in Table 3-2 to illustrate the Study Area’s general air quality trends. 2016 data becameavailable following the publication of the Draft SEIS and has been included in this revised memorandum.

3.3 Pollutant DescriptionPlease refer to Section 3.2 of the Westside Subway Extension Air Quality Technical Report (August 2010)for descriptions of air pollutants.

3.4 Attainment StatusSection 107 of the 1977 Clean Air Act Amendment requires that the USEPA publish a list of allgeographic areas in compliance with the NAAQS, plus those not attaining the NAAQS. Areas not inNAAQS compliance are deemed non-attainment areas. Areas that have insufficient data to make adetermination are deemed unclassified, and are treated as being attainment areas until provenotherwise. An area’s designation is based on the data collected by the state monitoring network on apollutant-by-pollutant basis.

The Project’s Study Area is located in Los Angeles County. As shown Table 3-3, the USEPA has classifiedLos Angeles County as a nonattainment area for ozone, PM2.5, and lead. Los Angeles County is listed as amaintenance area for carbon monoxide and PM10, as it was previously a nonattainment area for thesepollutants.

3.5 State Implementation Plan and Transportation Improvement ProgramPlease refer to Section 3.5 of the Westside Subway Extension Air Quality Technical Report (August 2010)for information about the State Implementation Plan and Transportation Improvement Program (STIP).

3.6 Land UsesThe air-quality-sensitive land uses, such as residences, parks, schools, day care centers, hospitals, andparks and playgrounds, have not changed from what was described in Section 4.4.2 of the Final EIS/EIR,with the exception of the opening of the medical rehabilitation facility on Century Park East and theapproved BHHS modernization program, which are described in this section and illustrated in Figure 3-1.The land uses immediately surrounding the Century City Constellation Station are primarily commercialwith high-rise residential planned for the northeast and southwest corners of Constellation Boulevardand Avenue of the Stars. A hotel currently occupies the southwest corner of this intersection. Adjacentto the proposed construction staging Century Park East are the BHHS campus and the medicalrehabilitation facility. Residential land uses also border Century Park West. Sensitive receptors for thisanalysis are identified in Section 4.2.1.2 of this memorandum.

Adjacent to and immediately south of the Century City Constellation construction staging site onCentury Park East is a former physician-run hospital at 2070 Century Park East. This facility was closed in2008 due to funding issues and recently reopened under new ownership as a remodeled 9-story, 138-bed medical rehabilitation facility with inpatient services. The facility was not in operation at the time ofthe Final EIS/EIR studies; therefore, the analysis of the adjacent construction staging area did not assesspotential impacts to the facility.

Located immediately east of the Century City Constellation construction staging area is BHHS, which isundergoing a modernization of its campus. Construction activities for the campus began in 2015 and arescheduled through 2020, meaning some BHHS construction activities will coincide with constructionactivities for Section 2. In 2008, BHUSD issued the Draft Master Plan that was accepted by the CaliforniaBoard of Education and became final in 2010. The BHUSD Master Plan EIR was completed in 2015. Asshown in Figure 3-1, the BHHS modernization program as analyzed in the BHUSD Master Plan 2015 EIRincludes:

n Improvements/modifications to Buildings A (Main Classrooms), B1 (Domestic Science), B2 (OldClassrooms), Building B3 (Peters Auditorium), Building B4 (Salter Wing), Building F (Swim Gym), andBuilding L (Science Laboratories)

n Construction of a new athletics building with subterranean parking

n Construction of an aquatics center

n Demolishment of Building E (Gymnasium) and Building H (Maintenance & Operations; Moreno HighSchool)

n Reconfiguration of athletic fields

n New pedestrian plaza, enhancements to “graduation lawn”, and conversion of Heath Ave into apedestrian walk

n Existing parking garage in Building A used by students and staff will remain, but circulation downHeath Avenue will be eliminated.

In total, the modernization will increase BHHS campus parking from 544 spaces to 712 spaces. Duringconstruction, portable classrooms will temporarily be located on the current lacrosse fields, which areimmediately to the east of and adjacent to the Century City Constellation Station construction stagingareas.

4.0 ENVIRONMENTAL IMPACT/ENVIRONMENTAL CONSEQUENCES4.1 Operational ImpactsThere have been no changes with regards to the operations of the Project, the analyses containedwithin Sections 4.1 and 4.2 of the Westside Subway Extension Air Quality Technical Report (August 2010)and Sections 3.1, 3.2, and 3.3 of the Westside Subway Extension Project Air Quality Memorandum(December 2011) remain valid. It should be noted that the Project was presented at the SouthernCalifornia Association of Governments Transportation Conformity Working Group in June 2017, and itwas unanimously determined that it is not a project of air quality concern. Please refer to thesedocuments for further information on the operational impacts of the project.

4.2 Construction ImpactsThis Air Quality Technical Memorandum addresses the impacts of the construction of the Century CityConstellation Station and tunneling activities associated with Section 2 of the Project. The removal ofthe double crossover at the Wilshire/Rodeo Station shortens the station box by 950 feet. This shorteningof the underground station would result in slightly reduced construction impacts due to a smallerconstruction footprint along Wilshire Boulevard, reduced time needed for station excavation, and fewertruck trips needed for hauling excavated material. Therefore, the Wilshire/Rodeo Station is not thesubject of this air quality evaluation.

As there have been no other changes to the operations or the construction elements of the other sections ofthe Project, the analyses contained within Section 4.3 of the Westside Subway Extension Air Quality TechnicalReport (August 2010), Sections 3.4 of the Westside Subway Extension Project Air Quality Memorandum(December 2011), and the Westside Subway Extension Project Air Quality Construction ImpactsMemorandum (May 2012) are still valid. Please refer to these documents for further information on theconstruction impacts of the project outside of the Century City Constellation Station.

4.2.1 Century City Constellation StationThe Century City Constellation Station would serve as a launch site for Tunnel Boring Machines (TBMs) andthe location for the equipment needed to support operation of the TBMs. Approximately 3 acres ofconstruction staging and laydown area are needed at this station to support station construction andtunneling activities. The construction staging has changed since publication of the Final EIS/EIR due to aproposed development on the northeast corner of Constellation Boulevard and Avenue of the Stars. Figure4-1 depicts the construction staging locations. Refer to Chapter 2 of the Final SEIS for a detailed description ofthe construction activities at the Century City Constellation Station. The construction staging sites include twolocations along Century Park East and require full acquisition of or temporary construction easements at1940 Century Park East (Area 2), 1950 Century Park East (Area 2), and 2040 Century Park East (Area 3).

In response to comments on the Draft SEIS to consider alternative construction staging options, theapproach to the construction staging was revised as shown in Figure 4-2. The tunnel ventilation exhaustducts will be extended to Area 3 and the tunnel exhaust will be vented through scrubbers. In addition,instead of being located in Area 3, the muck from the tunnel will be stockpiled in Area 2, adjacent to thetunnel access shaft, and trucks will haul the muck from Area 2 primarily during nighttime hours. Thischange was proposed since the Draft SEIS to improve the efficiency of construction activities and reduceconstruction noise and vehicle emissions next to BHHS. By moving the storage and load out of thetunnel muck to a location adjacent to the tunnel access shaft, the conveyor belt running between Areas

2 and 3 is no longer needed, but the materials transport corridor remains to allow for the movement ofmaterials and equipment between Area 2 and Area 3 and as a location for tunnel support equipmentand materials storage.

Figure 4-1: Century City Station Construction Staging Sites

The specific equipment assumptions have also been refined since publication of the Draft SEIS, andthese new assumptions are detailed in Section 4.2.1.1 of the Century City Constellation Station AirQuality Technical Memorandum – Revision 2. Several pieces of equipment have been added to theanalysis, including vacuum trucks and additional loaders at certain locations. Specific pieces ofequipment are also required to be Tier 4, such as several cranes, loaders, and welding units. Specificpieces of equipment are also required to be no higher than Tier 2, due to safety issues within the tunnel.

Page 4-4

In summary, the following refinements have been made to the construction assumptions sincepublication of the Draft SEIS:

n Moving the tunnel muck stockpile and segment storage to Area 2

n Moving the tunnel exhaust fan discharge to Area 3

n Muck loading at night at Area 2 instead of Area 3

n Front end loader operating at Area 2 instead of Area 3

n Compressor plant relocated from Area 3 to Area 2

n Water treatment plant relocated from Area 2 to Area 3

n Foam plant relocated from Area 3 to Area 2

Elements related to construction staging at the Century City Constellation Station include the following:

n Installation of a Tunnel Access Shaft in Area 2 (1940 Century Park East) : A temporary access shaft,approximately 80 feet in diameter, will be constructed in Area 2 to provide access to the tunnel forworkers and materials and to remove excavated material from the tunnel. Construction stagingactivities in Area 2 will occur for approximately seven years. In response to comments on the DraftSEIS to consider alternative construction staging options, the approach to the construction stagingwas revised. The tunnel ventilation exhaust ducts will be extended to Area 3 and the tunnel exhaustwill be vented through scrubbers. In addition, instead of being located in Area 3, the muck from thetunnel will be stockpiled in Area 2, adjacent to the tunnel access shaft, and trucks will haul the muckfrom Area 2 primarily during nighttime hours. This change was proposed since the Draft SEIS toimprove the efficiency of construction activities and reduce construction noise and vehicle emissionsnext to BHHS (Figure 4-1).

n Materials Transport Corridor between Area 2 and Area 3: A materials transport corridor will beestablished for approximately five years to connect the tunnel access shaft in Area 2 with stagingactivities in Area 3 to provide for movement of equipment and materials between the two sites andspace for tunnel support equipment and materials. Three options for the materials transport corridor areproposed: 1) along the east side of the AT&T building at 2010 Century Park East; 2) along the west side ofthe AT&T building with a closure of a northbound lane on Century Park East; or 3) use the east side of theAT&T building for storage and fixed equipment while using the west side of the AT&T building formovement of equipment and materials. The conveyor belt proposed in the Draft SEIS is no longerrequired for transporting muck to Area 3. Under Option 2 and Option 3, a partial closure of Century ParkEast (northbound lane along the west side of the AT&T building) may occur for a period of construction.The lane would be used by construction vehicles, which would reduce construction activity along theeast side of that building adjacent to BHHS. This change was proposed since the Draft SEIS to improvesafety of the construction staging area, improve the efficiency of construction activities, and reduceconstruction noise and vehicle emissions next to BHHS.

n TBM Launch Box and Station Box Construction (Area 4): The Century City Constellation Station boxwill be constructed within Constellation Boulevard with a TBM launch box located on the easternend of the Century City Constellation Station box. Phased lane closures consisting of sequencedpartial and full street closures will be required on Constellation Boulevard to support the TBM launchbox and station box construction activities.

n Use of Existing Bus Layover Area for Construction Material Storage (Area 5): A material storagearea will be placed at the existing 0.3-acre bus layover site on the southeast corner of Century ParkWest and Constellation Boulevard. The site will be used for approximately seven years for traileroffices, storage of construction materials, and parking for construction equipment associated withconstruction of the station. Following construction of the station, the site will be returned to itscurrent use as a bus layover facility.

n Temporary Bus Layover on Santa Monica Boulevard: Due to the use of the existing bus layover site(Area 5) for construction material storage, a new temporary bus layover approximately 500 feet longand 12 feet wide and providing parking for up to five buses will be constructed in the median ofSanta Monica Boulevard between Avenue of the Stars and Century Park East and will be in use forapproximately seven years.

n Ventilation/Exhaust Structures into the Westfield Century City Property: Metro will requiretemporary and permanent easements into the Westfield Century City mall property (Westfield Mall)for the purpose of constructing ventilation ducts to service the subway.

All construction staging areas would be surrounded by a 20-foot noise barrier wall, which would servethe dual purpose of mitigating noise as well as providing a security measure to prevent trespassers fromaccessing the construction sites.

Figure 4-3 summarizes the project schedule for Section 2 of the Project, which is consistent with theconstruction timeline presented in the Final EIS/EIR. Section 2 early construction activities began in late2016 and are expected to last through 2019. These early construction activities include survey work,utility relocation, and preparation of staging areas, which includes real estate acquisition anddemolition, fencing and securing the staging areas, and leveling and graveling the staging areas tocontrol dust and water runoff.

Major construction activities could begin as early as January 2018 with clearing and demolition onstaging and laydown sites in advance of piling for the station box. Work at the Wilshire/Rodeo andCentury City Constellation Stations, from the commencement of temporary station shoring and streetdecking to the removal of street decking and street reinstatement, would take approximately sevenyears to complete.

Construction of the Century City Constellation Station would begin with the piling and excavation of theTBM launch box, which would be located within the eastern end of the station box. The piling anddecking of the TBM launch box will take approximately three to five months, with excavation of the TBMlaunch box taking another five to six months. Once the TBM launch box is excavated, it would takeapproximately nine months to assemble and launch the TBM within Constellation Boulevard.

In total, the station box piling and decking of the Wilshire/Rodeo and Century City Constellation Stationswould last approximately 12 to 15 months and would consist of the installation of excavation support,installation of dewatering and instrumentation wells, removal of street pavement and subgrade, andinstallation of deck beams and precast concrete deck panels. Following the piling and decking, thestation box excavation would extend for another year.

Once the TBMs are launched from the station box within Constellation Boulevard, they would tunneleastward toward the Wilshire/La Cienega Station, which will be completed as part of Section 1.Tunneling of Section 2 is anticipated to extend from late 2019 through the end of 2020. Starting in mid-2020, excavation work would begin on cross-passages, tunnel inverts, and walkways, which wouldextend into 2022. This three-year period of tunneling and excavation activities would be the mostintense construction period, with excavated materials removed through the access shaft in Area 2 andhauled away in trucks. Other activities to support tunneling would include slurry pumping and deliveryof segments and tunnel supplies via the access shaft in Area 2.

Station construction activities would last four to five years and would include forming and placingconcrete station structures and installing architectural and mechanical elements. The system installationand facilities, which would begin in 2022 and last approximately two years, would consist of installationof the trackbed, rail, and third rail (traction power); conduits for systems installations; electricalsubstations; and communications and signaling. The station backfill and street restoration would beginin 2023 and would take approximately a year to complete.

Once construction activities are complete, system testing and pre-revenue operations would begin inlate 2024 and last through early 2026. Section 2 revenue operations are anticipated to commence in2026.

4.2.1.1 Emission Burden AnalysisAn assessment of the air quality construction impacts of the Century City Constellation Station, utilizingthe above-described staging information and schedule, was conducted. This assessment used emissionfactors from the CARB model for off-road vehicle and equipment emissions (OFFROAD), as well as theCARB model for on-road vehicle emissions (EMission FACtor program, or EMFAC). For the off-roadvehicles and equipment, SCAQMD-specific OFFROAD 2011 emission factors, along with project-specificinformation on pieces of equipment for each construction phase, were used. For each piece of

equipment, the CARB equipment type, number of pieces of equipment, horsepower and utilization wereprovided by project engineers. In addition, specific pieces of equipment are required to meet Tier 4 finalemission standards. EPA adopted multiple tiers of emissions standards for off-road equipment rangingfrom Tier 1 to Tier 4, with Tier 4 being the most stringent. Tier 4 engines reduce NOx and PM emissionsby over 90% as compared to older model engines. Tier 4 standards were modeled as such following theprocedures outlined in the California Emissions Estimator Model (CalEEMod)program. Equipment thatmust meet the Tier 4 final emission standards when used for surface operations include:

n Crane

n Loader

n Excavator

n Telehandler

n Bore/Drill Rig

n Front End Loader

Equipment that is being used for specific subsurface operations was modeled as Tier 2. Higher tieredequipment has not been approved for use by the Mining Safety and Health Administration for specificsubsurface operations. This equipment includes:

n Telehandler

n Excavator

n Loader

Vacuum trucks and an increased number of loaders were analyzed in addition to the equipmentanalyzed in Revision 1 of this memorandum. Tier specific emission rates were obtained from CalEEMod.In addition, a material handler has been specified for the project and the equipment-specific emissionrates, as supplied by the contractor, have been applied to the study. All other pieces of equipment wereassumed to be a mix of 40 percent fleet average emissions and 60 percent Tier 4 equipment, definedusing CARB’s OFFROAD model.

Worker and delivery trip emissions factors were estimated using the EMFAC2014 emission factor model.All trucks used for hauling and deliveries are required to be model year 2012 or newer.

For this revised analysis, an extension of the tunnel ventilation exhaust ducts from Area 2 to Area 3 wasmodeled. This revision allows for the exhaust from the Tier 2 equipment used in the tunnel (segmenthauler, loader, etc.) to be vented farther from specific sensitive receptors, such as the temporaryclassrooms for BHHS. To account for the use of extended exhaust ducts, the exhaust was modeled as apoint source rather than an area source.

In addition to exhaust emissions from the construction equipment, fugitive dust emissions from dirthandling and re-entrained roadway dust were also included in the emission burden analyses to presenta full inventory of emission burdens generated by the project. Emissions from earthmoving activities(bulldozing, etc.), truck loading, road dust, etc. were calculated using applicable formulas from EPA’s AP-42 (https://www.epa.gov/air-emissions-factors-and-quantification/ap-42-compilation-air-emission-

factors). Area-specific parameters, such as silt content, were taken from the CalEEMod program. Soilmoisture content was updated to reflect the muck moisture content based on Section 1 field datainformation. Detailed construction emission spreadsheets are contained in Appendix A of thismemorandum.

Using these various data sources, daily construction emission levels were developed. These values werecompared to the air quality construction significance thresholds shown in Table 4-1 to determine if theproject would meet or exceed these values.

Notes:Total construction emissions may not occur during the same peak period as each emission source, therefore the totalconstruction emissions shown may not add up to the sum of the elements presented in this table. Peak construction emissionsfor all pollutants are predicted in the year 2020.

The regional emissions presented in Table 4-2 are those associated with construction of the Century CityConstellation Station. These emission estimates are based upon updated models and information sinceissuance of the Final EIS/EIR and subsequent air quality analyses in 2012 and 2015. These updatesinclude refinement of the construction emissions model reflecting project-specific equipment, includingelectrification of specific pieces of equipment, Tier 4 Final emission standard requirements for specificpieces of equipment, and detailed equipment placement and usage. Due to these changes, theemissions presented in this report are significantly lower than those presented in the Final EIS/EIR andthe Westside Subway Extension Project Air Quality Memorandum (Metro 2011) for a typical station witha TBM entry/exit site.

Emissions of VOC, NOx and PM2.5 presented in this report are also lower than those presented in theWestside Subway Extension Project Air Quality Construction Impacts Memorandum (Metro 2012) for atypical station with a TBM entry/exit site under the Phased Construction Scenario after Mitigation (Table3-5 in the Westside Subway Extension Project Air Quality Construction Impacts Memorandum (Metro

2012), while emissions of CO and PM10 presented in this report are slightly higher (by 8 and 6 poundsper day, respectively) than those presented in the Westside Subway Extension Project Air QualityConstruction Impacts Memorandum.

Estimated emissions of VOC, NOx, PM10, and PM2.5 are also lower than those presented in the Addendumto the Final Environmental Report (Metro 2015) for the Century City Constellation Station afterMitigation (Table 4 in the Addendum to the Final Environmental Report), while emissions of CO areslightly higher (by 12 pounds per day) in this report.

As such, emissions associated with larger portions of the Project (i.e. Section 2) would be significantlylower than those presented in the Final EIR/EIS and, with the exception of CO and PM 10, lower thanthose presented in the Westside Subway Extension Project Air Quality Construction ImpactsMemorandum and the Addendum to the Final Environmental Report.

4.2.1.2 Microscale AnalysisA microscale (localized) air quality analysis was conducted to assess the potential impacts ofconstruction activities. This analysis, which follows the guidelines in SCAQMD’s Final LocalizedSignificance Threshold Methodology, shows the project’s local impacts on criteria pollutants of PM2.5,PM10, NO2 and CO. For this analysis, refined modeling was conducted using USEPA’s AtmosphericDispersion Model (AERMOD), along with the emissions burdens estimated from the above constructionemission burden analysis. The analysis followed SCAQMD’s Modeling Guidance for AERMOD(http://www.aqmd.gov/home/library/air-quality-data-studies/meteorological-data/modeling-guidance)along with USEPA’s Guideline on Air Quality Models, updated on January 17, 2017(https://www3.epa.gov/ttn/scram/appendix_w-2016.htm). This guidance details modelingrequirements, including the requirement to model with and without terrain and the application of areceptor grid to identify the maximum predicted concentrations.

Dispersion models use mathematical formulations to characterize the atmospheric processes thatdisperse pollutants emitted by emission sources, which in this case are the emissions generated by theconstruction equipment and vehicles operating within the project area. As directed by the guidance, theAmerican Meteorological Society/ Environmental Protection Agency Regulatory Model (AERMOD)Version 16216r was used to determine microscale pollutant concentrations. AERMOD is a steady-stateplume model. AERMOD incorporates current concepts about flow and dispersion in complex terrain.AERMOD is currently USEPA’s state-of-the-art model for predicting pollution concentrations fromemission sources. Based on estimated emission rates and meteorological inputs, AERMOD was used topredict pollutant concentrations at the selected receptor locations. Five years of meteorological data(2008 to 2012) from SCAQMD’s West LA (WSLA) meteorological station were input into the AERMODprogram. The AERMOD input and output files are contained in Appendix B. Other AERMOD parametersare discussed below.

Receptors and Model LayoutFigure 4-4 presents the AERMOD model layout. The construction activities are shown in as the Metrostaging areas. There are currently 13 areas where construction activity/hauling of material is planned tooccur. The red crosses represent receptor locations. These are the locations where pollutantconcentrations from construction activities are estimated. A total of 5,023 receptors were analyzed. Asshown in Figure 4-4, receptors were laid out in a grid pattern to help ensure that the highest pollutant

contribution from the project is captured. As per the direction of SCAQMD, a grid system of receptorswas laid over the study area, at a height of 0.0 meters. In addition to the grid receptors, receptors wereplaced at sensitive land uses, including residences, schools, hotels, and medical facilities, adjacent toconstruction staging areas or haul routes, including the following:

These receptors are expected to capture the highest concentrations from the emissions of constructionequipment in the staging areas and vehicles on the roadways. While the analyses estimated pollutantconcentrations at all of the receptors shown, only the maximum estimated concentration at eachreceptor is provided in the results.

AERMOD Modeling ParametersAERMOD Microscale modeling is used to predict concentrations resulting from emissions fromconstruction equipment and vehicles operating within the project area. Several parameters are usedwithin the model to predict these concentrations. These include:

n Terrain – As per SCAQMD guidance, the model was run both with flat terrain and actual terrain toensure that the worst-case conditions have been analyzed. Results presented represent the worstcase of these two scenarios.

n Tier 2 – The Tier 2 modeling approach, with an ambient NOx/NO2 ratio of 0.5 for one hour and anambient NOx/NO2 ratio of 0.75 for annual, was used to predict pollutant concentrations.

n Worst-case day – Based on the results of the month by month regional burden analysis, the worst-case day for each pollutant was determined. For NO2 and PM, the worst-case day was determined tooccur in September of 2020. For CO, the worst-case day was determined to occur in August of 2020.During both of these time periods, the following construction locations, in addition to the haulroutes, are scheduled to be active:

– Site 2040 (Area 3)

– Site 1950 (Area 2)

– Site 1940 (Area 2)

– Station Box (Area 4)

n Hourly distribution of activities – A schedule of individual activities at each site was provided withthe overall schedule. Emissions resulting from these activities were distributed throughout thescheduled work day. For example, the tunneling activities at Site 2040 (Area 3) are scheduled to

occur over two shifts, one from 7:00 AM to 6:00PM and a second shift from 7:00 PM to 6:00 AM.The emissions resulting from this activity were evenly distributed during these time periods.

n Venting of exhaust emissions from tunnel boring operations – An exhaust shaft will be located atSite 2040 (Area 3). This shaft will carry the exhaust emissions from the tunnel boring operations andrelease them from a point source, approximately 20 feet high.

Background LevelsA background level must be added to this value to account for pollution entering the area from othersources. The background level is the component of the total concentration not accounted for throughthe microscale modeling analysis. Unique background levels, based on the specific details of theapplicable standards, and as recommended by USEPA and SCAQMD, have been added to modeledresults. The resulting pollutant concentrations (modeled result and background) were then compared tothe applicable NAAQS. As the West Los Angeles VA Hospital site is much closer to the study area, levelsfrom this location were applied if available. The following background concentrations were used:

n NO2: Recommended background calculation methodology was provided by SCAQMD based on datafrom the West Los Angeles VA Hospital monitoring site. SCAQMD recommended that the 1 hour NO 2

background value be based on the average of the last three years of monitored data using the 98thpercentile values from the SCAQMD historical database (http://www.aqmd.gov/home/library/air-quality-data-studies/historical-data-by-year) for the years 2014-2016 for the comparison to theNAAQS and the maximum 1-hour levels for the years 2014-2016 for the comparison to the CAAQS.Based on this information, the 1-hour NAAQS NO2 background is 50.9 ppb (95.6 μg/m3) and the 1-hour CAAQS NO2 background is 67.6 ppb (127.1 μg/m3). The annual average background value of13.3 ppb (25.0 μg/m3) is the maximum annual average value over the years 2014-2016.

n CO: the highest 1-hour and 8-hour maximums from the last three years (2014-2016) of monitoreddata from the West Los Angeles VA Hospital site were used for the 1-hour and 8-hour backgrounds.These values are 2.2 ppm for the 1-hour and 1.4 ppm for the 8-hour time period.

n PM10: Recommended background calculation methodology was provided by SCAQMD based on datafrom the North Main Street monitoring site, as this data is not collected at the VA Hospitalmonitoring location. SCAQMD recommended that the background levels be based on the maximum24-hour values from the last three years of monitored data from the SCAQMD historical database(http://www.aqmd.gov/home/library/air-quality-data-studies/historical-data-by-year). Based on thisinformation, the 24 hour PM10 background is 88 ug/m3. It should be noted that this background isbased on data that is acceptable for use under the CAAQS rather than the NAAQS. Using data that isacceptable for use under the NAAQS, the background would be lower. As such, the use of this higherbackground is considered conservative for comparison with the NAAQS.

PM2.5: The project area is currently non-attainment for PM2.5, and background concentrations of PM2.5

already exceed the NAAQS. As such, and according to SCAQMD guidance and direction (correspondenceprovided in Appendix D), PM2.5 increments have been compared to the significant change threshold forPM2.5 for construction, which is 10.4 μg/m3 (Table 4-1), rather than by adding the project impact to thebackground and comparing to the NAAQS. The significant change threshold represents the maximumcontribution from a project that is not expected to cause or contribute to an exceedance of the moststringent applicable federal or state ambient air quality standard.

presents the maximum levels modeled in the microscale analysis. As shown, there are predicted to beno exceedances of the NAAQS or CAAQS for CO, NO2 or of the significant change threshold for PM2.5.These lower levels as compared to the Draft SEIS are largely due to requiring certain pieces ofconstruction equipment to be Tier 4, venting the emissions from tunnel boring operations, and requiringhauling trucks to be model year 2012 or newer.

*Note: As per SCAQMD email on October 10, 2016 (provided in Appendix D), since the SCAQMD is nonattainment for PM 2.5 and backgroundvalues already exceed both the NAAQS for the 24 hour and annual time periods, the PM2.5 increment should be compared to the SCAQMDsignificant change threshold for 24 hour PM2.5 for construction only.**Numbers may not add up exactly due to rounding.ppb = parts per billion; ppm = parts per million; μg/m3 = micrograms per cubic meter

No exceedances of the PM10 NAAQS are predicted to occur with the Project.

Exceedances of the PM10 CAAQS are predicted to occur at all the receptors analyzed because thebackground level for the area is already over the PM10 CAAQS. Of the over 5,000 receptors analyzed, 15are predicted to demonstrate increased PM10 levels above the 10.4 μg/m3 significant change thresholddeveloped by SCAQMD (Figure 4-5). Several of these receptors are located on the northwest corner ofthe site of the temporary classrooms on the BHHS campus, medical rehabilitation facility, and theremainder are in the same general vicinity. The levels over 10.4 ug/m 3 are predicted to occur inSeptember 2020 and may occur at any time during the 20 hours/day that construction activities areunderway. This is the month when the highest PM10 emissions from off-road construction equipment ispredicted to occur along with increased emissions from material hauling.

Page 4-16

Figure 4-5: Locations of Receptors Predicted to Exceed PM10 Significant Change Threshold

As shown in Figure 4-6, it is predicted that the emission burdens generated from the on-siteconstruction equipment will be lower for every other month of construction. The majority of the PM 10

emissions contributing to these levels comes from dirt activity. Mitigation measures that are alreadyproposed for the Project, such as street sweeping (CON-15) and the presence of noise barriers aroundthe construction site, are recognized by the SCAQMD to reduce dust emissions by 30 to 74 percent andby 25 to 60 percent, respectively. Implementation of these mitigation measures could be optimized inorder to reduce PM10 dust emissions to below the SCAQMD significant change threshold of 10.4 μg/m3.

The estimated maximum localized pollutant levels are based on expected production rates andequipment utilization. This information is often limited since it does not take into account the actualequipment on site and construction techniques that the contractor will actually employ. As such,predicted concentrations will be verified before construction is initiated, as described in CON-90.

As discussed in more detail in the Mitigation Measures section below, based on the results of theverified analysis, the contractor will be mandated to alter operating procedures/schedule/ equipment ifan exceedance of the applicable standards is predicted. The contractor will be required to keep a log ofconstruction equipment used during construction along with hours of operation of each specific piece ofequipment to ensure that construction activities are not in exceedance of applicable air qualitystandards and provide reports on a quarterly basis.

Figure 4-6: PM10 Monthly Emissions as a Percentage of Maximum Concentration

4.2.1.3 Health Risk AnalysisA population-wide health risk assessment was conducted to determine the potential health risks causedby the construction of the Project. The Hotspots Analysis and Reporting Program Version 2 (HARP2) RiskAssessment Standalone Tool (RAST) was used to analyze cancer, chronic, 8-hour chronic, and acutehealth risks associated with inhalation of pollutants of concern. Other exposure pathways were notevaluated, as this analysis only considers air pollutants. The pollutants of concern analyzed in this healthrisk assessment were diesel particulate matter, carbon monoxide, and nitrogen dioxide (NO 2). Eachpollutant generated a risk value.

To account for sensitive receptors, the most conservative analysis (70-year resident, population-wide)was performed along with a 30-year exposure analysis. The cancer risk value indicates the number ofindividuals that develop cancer per million individuals due to exposure to a pollutant over an assumedlifetime of 70 years. HARP2 RAST uses the annual average air concentration of a pollutant, the knowncancer inhalation slope factor for the pollutant, and the Office of Environmental Health HazardAssessment (OEHHA) derived intake rate percentile (resident) to calculate cancer risk. A ratio wasapplied to the cancer risk probability to account for project duration.

Non-carcinogenic chronic risk is determined by calculating hazard quotients and indices. A hazardquotient is calculated for each organ system affected by inhalation of a pollutant. A hazard index is thesum of each hazard quotient for a pollutant. HARP2 RAST contains a database with information on whichpollutant affect which organ system(s). Using the average annual air concentration of a pollutant and

the known non-carcinogenic chronic inhalation reference exposure level for the pollutant, HARP2 RASTcalculates hazard quotients according to each affected organ system for a certain pollutant.

Similarly, non-carcinogenic acute risk is calculated by HARP2 RAST using the maximum hourlyconcentration of a pollutant, affected organ systems, and the known non-carcinogenic acute inhalationreference exposure level for the pollutant.

The analysis used the latest version of the HARP2 RAST. Cancer risk assessments were conducted fordiesel particulate matter and NO2. Results from AERMOD modeling for sensitive receptors were used inthe HARP2 analysis. Using these parameters with an average daily pollutant concentration calculatedbased on the maximum construction emission burdens, a 5-year conservative exposure of 12 hours perday, 225 school days a year, the excess cancer risk did not exceed the SCAQMD excess cancer riskthreshold of 10 in a million. A five-year exposure was used because construction activities generatinghigh pollutant concentrations at the locations near BHHS, such as tunneling and station excavation, areexpected for less than five years. The results of this analysis are summarized in Table 4-4. Results for theRehabilitation Center and for the temporary BHHS classrooms are presented in this table.

4.2.1.4 Odor AssessmentThe Final EIS/EIR discloses the potential for construction activities to generate objectionable odors. Asdescribed in the Final EIS/EIR, the potential for objectionable odors could be significant but would belimited to the duration of construction. The only difference in identified impacts for the currentconstruction analysis, as compared to the Final EIS/EIR, is the timing of the potential odor impacts, asthe construction schedule has been refined since issuance of the Final EIS/EIR.

While offensive odors rarely cause physical harm, they can be considered to be unpleasant. Anytemporary odor impacts during construction would be directly related to the exhaust from diesel-fueledconstruction equipment. As such, many of the mitigation measures proposed in the Final EIS/EIR for thereduction of air quality emission impacts would also be effective in limiting odor impacts from theconstruction equipment, such as CON-8—Monitoring and Recording of Hazardous Gasses at Worksites.According to CEQA, Appendix G, the significance of odor impacts is related to the number of complaintsreceived. If, during construction, the project “creates objectionable odors affecting a substantial numberof people” (per CEQA, Appendix G), Metro will investigate other potential measures, if practicable, tomitigate the impacts.

Other such mitigation measures identified in the Final EIS/EIR that would be effective in limiting odorimpacts include CON-9—No Idling of Heavy Equipment; CON-10—Maintenance of ConstructionEquipment; CON-11—Prohibit Tampering of Equipment; CON-12—Use of Best Available EmissionsControl Technologies; and CON-13—Placement of Construction Equipment. Furthermore, the placementof temporary noise barriers could be optimized to break the line-of-sight from exhaust sources tosensitive receptors in the vicinity of construction areas, thereby deflecting direct exposure to anypotential odorous emissions from construction equipment.

As discussed in the Final EIS/EIR, operations of the project would not cause any objectionable odors.

4.2.1.5 Conformity AssessmentRefer to Section 4.4 of the Westside Subway Extension Air Quality Technical Report (August 2010) forinformation about the conformity assessment.

4.3 Cumulative Impact from ConstructionCumulative impacts are impacts on the environment that result from the incremental impact of aproject when added to other past, present, and reasonably foreseeable future actions regardless ofwhat agency (Federal or non-Federal) or person undertakes such other actions. Cumulative impacts canresult from individually minor but collectively significant actions taking place over a period of time. (40CFR § 1508.7).

As discussed earlier, the BHHS campus, which is located immediately east of the Century CityConstellation construction staging area, will be undergoing modernization. Construction activities forBHHS began in 2015 and are scheduled to continue through 2020, which means some BHHSconstruction activities will coincide with construction activities for the Century City Constellation station.Table 4-6 presents the maximum daily construction emissions burdens for BHHS as compared toSCAQMD daily thresholds, as presented in the BHHS Master Plan 2015 EIR (BHUSD 2015). As shown,SCAQMD thresholds would be exceeded for NOx.

There is a potential for cumulative construction impacts if peak construction emissions from the CenturyCity Constellation station and BHHS construction activities take place simultaneously, where thecombined effect could have the potential to exceed SCAQMD thresholds. As shown in Table 4-6,emissions of NOx from BHHS construction activities are predicted to exceed SCAQMD thresholds.However, as noted in the footnote to Table 4-6, peak BHHS construction emissions for the majority ofpollutants (CO, NOx, PM10 and PM2.5) were predicted to occur in late 2016. As demolition has started forBHHS, it is anticipated that the peak will occur prior to the start of major construction activities for theCentury City Constellation Station, which would not commence until 2018. Peak BHHS constructionemissions for VOCs are predicted to occur in early 2020. However, even if BHHS construction is delayedand peak BHHS VOC emissions (59.7 lbs/day) are added to peak Century City Constellation station VOCemissions (4 lbs/day), the total (63.7 lbs/day) combined emissions would still be below the SCAQMDthreshold.

There is also a potential for cumulative construction impacts if construction of the new Century CityCenter should take place at the same time as the Century City Constellation Station. The schedule andactivities associated with construction of the Century City Center are currently unknown. However, asshown in Table 4-7, the maximum daily construction emission burdens for Century City Center wouldnot exceed SCAQMD daily thresholds (Century City Center Draft Subsequent EIR, LSA 2013).

SCAQMD Thresholds 75 550 100 150 55

Source: Century City Center Draft Subsequent EIR, Table 4.4.AI (LSA 2013)

The peak construction emissions from the Century City Constellation Station are expected to occur inthe year 2020. As discussed above, peak emissions from the BHHS construction are expected to occurbefore construction of the Century City Constellation Station commences in 2018, and therefore beforepeak emissions would occur in 2020. Furthermore, construction of the Century City Center is notpredicted to exceed SCAQMD thresholds. As such, the potential overlap of construction of the CenturyCity Constellation Station, BHHS, and Century City Center are not expected to have the potential to besignificant. Therefore, no cumulative impacts are anticipated with construction of the various projects.

Refer to Section 4.5 of the Westside Subway Extension Air Quality Technical Report (August 2010) forinformation about cumulative impacts from project operations.

5.0 MITIGATIONThis section identifies air quality control measures to be used during construction. In addition to thosemeasures proposed in the Westside Subway Extension Air Quality Technical Report (August 2010), theWestside Subway Extension Project Air Quality Memorandum (December 2011), and the WestsideSubway Extension Project Air Quality Construction Impacts Memorandum (May 2012), two newmeasures, CON-90 and 97, have been added.

n CON-6—Meet Mine Safety (MSHA) Standards: Tunnel locomotives (hauling spoils and otherequipment to the tunnel heading) will be approved by Metro to meet MSHA standards.

n CON-7—Meet SCAQMD Standards: Metro and its contractors will set and maintain work equipmentand standards to meet SCAQMD standards, including NOx.

n CON-8—Monitoring and Recording of Hazardous Gasses at Worksites: Monitoring and recording ofhazardous gas levels at the worksites will be conducted. In areas of gassy soil, hazardous gas levelsin the underground working environment will be continually monitored and recorded. Constructionwill be altered as required to maintain a safe working atmosphere. The working environment will bekept in compliance with federal, state, and local regulations, including SCAQMD and Cal/OSHAstandards.

n CON-9—No Idling of Heavy Equipment: Metro specifications will require that contractors notunnecessarily idle heavy equipment.

n CON-10—Maintenance of Construction Equipment: Metro will require its contractors maintain andtune engines per manufacturer’s specifications to perform at USEPA certification levels, whereapplicable, and to perform at verified standards applicable to retrofit technologies. Metro will alsorequire periodic, unscheduled inspections to limit unnecessary idling and to ensure thatconstruction equipment is properly maintained, tuned, and modified consistent with establishedspecifications.

n CON-11—Prohibit Tampering of Equipment: Metro will prohibit its contractors from tampering withengines and require continuing adherence to manufacturer’s recommendations.

n CON-12—Use of Best Available Emissions Control Technologies: Metro will encourage its contractorsto lease new, clean equipment meeting the most stringent of applicable federal or state standards(e.g., Tier 3 or greater engine standards) or best available emissions control technologies on allequipment.

n CON-13—Placement of Construction Equipment: Construction equipment and staging zones will belocated away from sensitive receptors and fresh air intakes to buildings and air conditioners.

n CON-14—Measures to Reduce the Predicted PM10Levels: Mitigation measures such as watering, theuse of soil stabilizers, etc. will be applied to reduce the predicted PM10levels to below the SCAQMDdaily construction threshold levels. A watering schedule will be established to prevent soil stockpilesfrom drying out.

n CON-15—Reduce Street Debris: At truck exit areas, wheel washing equipment will be installed toprevent soil from being tracked onto city streets, followed by street sweeping as required to cleanstreets.

Page 5-2

n CON-16—Dust Control during Transport: Trucks will be covered to control dust during transport ofspoils.

n CON-17—Fugitive Dust Control: To control fugitive dust, wind fencing and phase grading operations,where appropriate, will be implemented along with the use of water trucks for stabilization ofsurfaces under windy conditions.

n CON-18—Street Watering: Surrounding streets at construction sites will be watered by trucks asneeded to eliminate airborne dust. In keeping with Metro’s prior policy on the Eastside Gold Line,the contractor will water streets in the station area impacted by dust not less than once a day andmore often if needed.

n CON-19—Spillage Prevention for Non-Earthmoving Equipment: Provisions will be made to preventspillage when hauling materials and operating non-earthmoving equipment. Additionally, speed willbe limited to 15 mph for these activities at construction sites.

n CON-20—Spillage Prevention for Earthmoving Equipment: Provisions will be made to preventspillage when hauling materials and operating earth-moving equipment. Additionally, speed will belimited to 10 mph for these activities at construction sites.

n CON-21—Additional Controls to Reduce Emissions: USEPA-registered particulate traps and otherappropriate controls will be used where suitable to reduce emissions of particulate matter andother pollutants at the construction site.

n CON-90—AERMOD Verification: The estimated maximum localized pollutant levels are based on aseries of assumptions made about contractor’s equipment and schedule. These levels will beverified, through additional AERMOD modeling, using the actual equipment and schedule proposedby the contractor prior to start of construction. Based on the results of the verification, thecontractor will be mandated to alter operating procedures/schedule/equipment if an exceedance ofthe applicable standards is predicted. Contractor will be required to keep a log of constructionequipment used during construction along with hours of operation of each specific piece ofequipment to ensure that modeled assumptions are verifiable based on field activity. It is expectedthat the contractor will supply plans and field data on a quarterly basis.

n CON-97—Install MERV 16-rated filters on the air intakes at the Beverly Hills High School temporaryclassroom site and medical rehabilitation facility. As these areas are predicted to potentiallyexperience air quality levels above the SCAQMD PM10 significance threshold for a limited timeperiod, the installation of these filters is recommended during this time period. MERV 16-ratedfilters are designed to control particulate contamination in the size range of 0.3 – 1.0 microns, whichis expected to reduce PM10 and PM2.5 levels within the buildings by over 95 percent.

The test data from the current study support a PM2.5/PM10 ratio of 0.1 for typical fugitive dust sources. This ratio takes into account the fact that most PM10 sample mass from uncontrolled dust sources is collected at PM10 concentrations exceeding 5,000 μg/m3.

• The PM2.5/PM10 ratio of 0.1 is also supported by numerous other studies including the prior field study that used dichotomous samplers as reference devices. It is possible that a ratio as low as 0.05 (as was found in the prior field tests of unpaved roads) might be appropriate, but this would require extrapolation of the current test data to higher PM10 concentrations.

- According to EPA publication: Gap Filling PM10 emission factors…, dismemberment has the same emission equation as batch drop operations which is also used for loading.

Hi Eddie, As I explained previously, for non-attainment pollutants, you would only compare the modeled concentrations to the significance change threshold and not add background. Since the Basin is non-attainment, that means the background concentrations currently exceed the AAQS therefore, it would not be possible for projects to add modeled concentrations to the background levels and still stay below the AAQS.

Hi Jillian,   I just was wondering if you could give me a bit of clarification on my below question from a few months ago.  Are we OK only comparing to the 24‐hour SCAQMD significance threshold for PM2.5 (10.4 ug/m3)?  Is there anything we need to consider for our annual PM2.5 results?     As I mentioned below, annual background design value for LA County of 12.3 ug/m3 is over the AAQS and the latest 24‐hour is almost over the AAQS (now at 34 ug/m3).   I just want to make sure we are understanding correctly.  Thanks again   Eddie

We are currently non‐attainment for PM2.5, so the CEQA threshold would be the significant change threshold and not adding the project impact to the background to check if you are under the AAQS.   Jillian Wong, Ph.D. South Coast AQMD 21865 Copley Drive, Diamond Bar, CA 91765 Direct: 909.396.3176

  Hello,   I’m looking for the correct person at SCAQMD to discuss the use of monitored data for background values in microscale PM modeling.  In brief, a project we are modeling is located midway between two AQ monitors in LA County.  We are using EPA design values from monitors in the area, and are curious as to the applicability of combining/averaging the background data from two monitors.    Thanks,   Edward Tadross  Supervising Planner – Environment WSP | Parsons Brinckerhoff 212-465-5266
